A flow-through vacuum degassing unit for degassing a mobile phase includes a vacuum conduit adapted to be connected to a source for creating a vacuum in the conduit, an inlet port and an outlet port for admitting and discharging the mobile phase to be degassed, a degassing tube for conducting the mobile phase through the conduit, wherein the degassing tube is a gas-permeable, liquid impermeable material. In a particular embodiment, the degassing tube receives multiple mobile phases blended together in a discrete volume of desired composition.

[ What is claimed is:] [1.]1. A method of degassing one or more liquids in a flow-through vacuum apparatus comprising:a) providing one or more distinct mobile phases for transport in a gas-permeable, liquid-impermeable degassing tube, said degassing tube being at least partially disposed in a sealed conduit, which conduit is adapted to be connected to a vacuum source for evacuating the conduit;b) providing a pump means for drawing the one or more mobile phases through the degassing tube;c) providing a liquid blending means for mixing said one or more distinct mobile phases into a single blended mobile phase stream; andd) positioning said degassing tube downstream from said blending means, and between said blending means and said pump means.
